Description

Technical Field

[0001] This utility model relates to the field of welding gasket technology, specifically a self-positioning, easily removable ceramic welding gasket. Background Technology

[0002] When welding metal workpieces, if a single-sided welding process is used, welding is only performed on the front of the base material. The welding backing is a backing material used to prevent the high-temperature molten liquid formed during the welding operation from flowing down through the gaps in the materials being welded. It is a ceramic product with good high-temperature resistance.

[0003] However, existing ceramic welding backings are used to weld continuous bottom-sealing welds, resulting in poor weld quality and the potential for sparks to damage the base material.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN218362610U discloses a ceramic backing structure for bevel welding, comprising a ceramic body and a fixing member for fixing the ceramic body at the bevel gap. The fixing member includes an aluminum foil tin plate and a fixing support body placed at the lower center of the aluminum foil tin plate. The upper end surface of the aluminum foil tin plate has an adhesive layer that is fixedly connected to the ceramic body. The aluminum foil tin plate includes an arc segment that fits against the lower end surface of the ceramic body and connecting ends placed on both sides of the arc segment that fit against the end face of the bevel. The fixing support body is placed at the lower center of the arc segment and includes a connecting block disposed at the lower end of the aluminum foil tin plate. Telescopic rods are horizontally connected to both sides of the connecting block. The telescopic rods have magnets that attract the bevel near the bevel. During welding, there is no need for manual fixing of the ceramic backing, avoiding molten iron overflow during welding and reducing welding defects.

[0005] The aforementioned device reduces molten iron overflow during welding by using the arc segment where the lower end face of the ceramic body fits together, thus reducing the weld seam. However, the arc segment where the lower end face of the ceramic body fits together only reduces molten iron overflow during welding. It is prone to misalignment during welding, which leads to a decrease in weld quality. Therefore, in actual use, there will be a situation where misalignment is prone to occur during welding, resulting in a decrease in weld quality. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The details of this self-positioning, easily removable ceramic welding gasket are as follows:

[0017] 1. The heat-conducting layer installed by the ceramic gasket concentrates the internal heat, and the heat is conducted to the arc-shaped seat through the heat-conducting holes in the ceramic gasket, thereby increasing the heat conduction and heat conduction area, forming good cooling efficiency and improving the welding quality;

[0018] Furthermore, the internal fixing blocks are protected by protective plates to reduce welding damage, the arc-shaped seat is fixed by positioning plates, and the connection points are reinforced by connecting ends, thereby improving the overall sealing performance and reducing welding defects.

[0020] Furthermore, the welding grooves opened on the inner side of the connection end make the temperature of the upper and lower surfaces of the weld metal uniform and produce a large penetration depth, improve the back-side forming effect of the weld, prevent the object from deforming, and thus improve the welding effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: Please refer to Figure 1 - Figure 6The present invention provides the following technical solution: a self-positioning and easily detachable ceramic welding gasket, comprising a ceramic gasket 1 and an arc-shaped seat 2, wherein an adhesive layer 6 is fixedly installed on the top of the ceramic gasket 1, and heat conduction holes 5 are opened on the inner side of the ceramic gasket 1; a positioning plate 8 is fixedly installed on the outer surface of the arc-shaped seat 2, and a positioning mechanism is provided between the arc-shaped seat 2 and the adhesive layer 6; an arc-shaped seat 2 is fixedly installed on the top of the ceramic gasket 1, and a magnet plate 7 is fixedly installed on the outer surface of the arc-shaped seat 2, and a disassembly and assembly mechanism is provided between the ceramic gasket 1 and the magnet plate 7.

[0030] The positioning mechanism between the arc-shaped seat 2 and the adhesive layer 6 facilitates the fixed connection of the ceramic gasket 1 to the bevel, thereby improving the welding quality and reducing welding defects. Furthermore, the disassembly and assembly mechanism between the ceramic gasket 1 and the magnet plate 7 facilitates personnel replacement and reduces welding losses.

[0031] Example 2: Based on Example 1, please refer to... Figure 1 - Figure 6 The positioning plate 8 was also disclosed, and its specific structure is as follows: a heat-conducting layer 3 is fixedly installed on the bottom surface of the ceramic gasket 1, a base 4 is fixedly installed on the bottom surface of the heat-conducting layer 3, and the heat-conducting layer 3 and the base 4 form an integral structure. A limiting block 9 is fixedly installed on the top of the positioning plate 8. A connecting end 11 is fixedly installed on the outer surface of the limiting block 9, and a welding groove 16 is opened on the inner side of the connecting end 11. A fixing block 13 is fixedly installed on the inner side of the connecting end 11. The positioning mechanism includes the fixing block 13. A protective plate 12 is fixedly installed on the outer surface of the fixing block 13, and the protective plate 12 and the fixing block 13 form an integral structure.

[0032] The heat-conducting layer 3 installed through the ceramic gasket 1 concentrates the internal heat, and the heat is conducted to the arc-shaped seat 2 through the heat-conducting holes 5 opened in the ceramic gasket 1. This facilitates the increase of heat conduction and heat conduction area, resulting in good cooling efficiency and improved welding quality. The internal fixing block 13 is protected by the protective plate 12 to reduce welding damage. The arc-shaped seat 2 is fixed by the positioning plate 8, and the connection end 11 is used to increase the fixation of the connection, thereby improving the overall sealing performance and reducing welding defects.

[0033] Example 3: Based on Example 1, please refer to... Figure 1 - Figure 6The protective plate 12 is also disclosed, and its specific structure is as follows: a strip base 10 is fixedly installed on the outer surface of the positioning plate 8, a ceramic gasket 14 is fixedly installed on the outer surface of the strip base 10, and the strip base 10 and the ceramic gasket 14 form an integral structure; a ceramic gasket 14 is fixedly installed on the outer surface of the connecting end 11, an aluminum foil tin plate 15 is fixedly installed on the outer surface of the ceramic gasket 14; the disassembly and assembly mechanism includes the connecting end 11, a magnet plate 7 is fixedly installed on the outer surface of the connecting end 11, a protective plate 12 is fixedly installed on the outer surface of the connecting end 11, the protective plate 12 is fixedly installed on the outer surface of the strip base 10, and the protective plate 12 is fixedly installed on the outer surface of the aluminum foil tin plate 15.
